Winter Tire Pressure
So, didn't really pay much attention last year when I switched out wheels, but was wondering what pressure to set my winter tires at..
S5 with winter wheels down a size to 18".
Do I go with the pressures on the door jam, or since it's a different size / winter tire, that I should keep different pressures?

Check the manual. I downsized my S-Line 19" to 18" and the manual has recommended tire pressures for different sizes. Off the top of my head my 245/40R18s were 33 front, 34 rear or something close to that.

the 18" i assume would be slightly higher profile I assume. Just use the door jam as a reference/ratio for front and rear... and go a few PSI lower than that.
